calculated saccharin drink intake volume combined water and saccharin-water intake to total water only intake ratio 2013-08-12T13:38:32Z A calculated measurement in which the entire volume of drink consumed during a specified period when that drink consists of both water with no additives and water with added saccharin, is divided by the entire volume of drink consumed during a separate but equivalent period when that drink consists only of water with no additives, and the result is presented as a ratio, fraction, quotient or percentage. The volume of drink is the size of the three dimensional space occupied by a liquid that is brought into the mouth and swallowed to quench thirst and/or for nourishment. Saccharin-water is saccharin, a cyclic imine of 2-sulfobenzoic acid which is 500 times sweeter than sugar and used as a nonnutritive sweetener, dissolved at a specified concentration in water, the clear, colorless, odorless, tasteless liquid each molecule of which contains one atom of oxygen and two atoms of hydrogen (H2O).
